[python] Re: Elliptical chainring

Hi Ghislain,

this looks very beautiful, a nice piece of work....
Tough I do not own (or be able to ride) a Phyton yet, I've got some other recumbents. I would like to try the oval chainring approach as well. Did you make them yourself? The way Giles described, drilling, sawing and filing? Or was there a CNC milling machine involved?
